| 摘 要： | 基于2008年ALOS和2010年"天绘一号"两期南宁市兴宁区遥感数据,应用NDVI像元二分方法得出研究区域的植被覆盖度情况,并与2010年林地利用类型图进行叠加对比分析。结果表明:南宁市兴宁区2010年植被覆盖度与2008年相比,中高植被覆盖度的面积增加,低覆盖度的面积减少;林地的植被覆盖度面积整体由高向低变化,由于林地面积的确定,林地对研究区域植被覆盖度的提高影响不明显。

| Abstract: | Based on ALOS in 2008 and Tianhui data in 2010 of Xingning area of Nanning City, the area vegetation cover- age was studied using NDVI pixel bisection method. Meanwhile, the thematic maps of area vegetation coverage were com- pared to the thematic maps of forestry land using in 2010. The results showed that, the area of medium-high vegetation coverage in 2010 compared to 2008 was increased, but the area of low vegetation coverage was reduced. The area of for- estry vegetation coverage was decreased, due to the stability of forestry area, the forestry showed little influence on the vegetation coverage increase in the total area. |
